81 | \end{center} | |
82 | ||
83 | ||
84 | The licenses for most software are designed to take away your freedom to | |
85 | share and change it. By contrast, the GNU General Public License is | |
86 | intended to guarantee your freedom to share and change free software---to | |
87 | make sure the software is free for all its users. This General Public | |
88 | License applies to most of the Free Software Foundation's software and to | |
89 | any other program whose authors commit to using it. (Some other Free | |
90 | Software Foundation software is covered by the GNU Library General Public | |
91 | License instead.) You can apply it to your programs, too. | |
92 | ||
93 | When we speak of free software, we are referring to freedom, not price. | |
94 | Our General Public Licenses are designed to make sure that you have the | |
95 | freedom to distribute copies of free software (and charge for this service | |
96 | if you wish), that you receive source code or can get it if you want it, | |
97 | that you can change the software or use pieces of it in new free programs; | |
98 | and that you know you can do these things. | |
99 | ||
100 | To protect your rights, we need to make restrictions that forbid anyone to | |
101 | deny you these rights or to ask you to surrender the rights. These | |
102 | restrictions translate to certain responsibilities for you if you | |
103 | distribute copies of the software, or if you modify it. | |
104 | ||
105 | For example, if you distribute copies of such a program, whether gratis or | |
106 | for a fee, you must give the recipients all the rights that you have. You | |
107 | must make sure that they, too, receive or can get the source code. And | |
108 | you must show them these terms so they know their rights. | |
109 | ||
110 | We protect your rights with two steps: (1) copyright the software, and (2) | |
111 | offer you this license which gives you legal permission to copy, | |
112 | distribute and/or modify the software. | |
113 | ||
114 | Also, for each author's protection and ours, we want to make certain that | |
115 | everyone understands that there is no warranty for this free software. If | |
116 | the software is modified by someone else and passed on, we want its | |
117 | recipients to know that what they have is not the original, so that any | |
118 | problems introduced by others will not reflect on the original authors' | |
119 | reputations. | |
120 | ||
121 | Finally, any free program is threatened constantly by software patents. | |
122 | We wish to avoid the danger that redistributors of a free program will | |
123 | individually obtain patent licenses, in effect making the program | |
124 | proprietary. To prevent this, we have made it clear that any patent must | |
125 | be licensed for everyone's free use or not licensed at all. | |
126 | ||
127 | The precise terms and conditions for copying, distribution and | |
128 | modification follow. | |

132 | Modification} | |

136 | %\renewcommand{\theenumi}{\alpha{enumi}} | |
137 | \begin{enumerate} | |
138 | ||
139 | \addtocounter{enumi}{-1} | |
140 | ||
141 | \item | |
142 | ||
143 | This License applies to any program or other work which contains a notice | |
144 | placed by the copyright holder saying it may be distributed under the | |
145 | terms of this General Public License. The ``Program'', below, refers to | |
146 | any such program or work, and a ``work based on the Program'' means either | |
147 | the Program or any derivative work under copyright law: that is to say, a | |
148 | work containing the Program or a portion of it, either verbatim or with | |
149 | modifications and/or translated into another language. (Hereinafter, | |
150 | translation is included without limitation in the term ``modification''.) | |
151 | Each licensee is addressed as ``you''. | |
152 | ||
153 | Activities other than copying, distribution and modification are not | |
154 | covered by this License; they are outside its scope. The act of | |
155 | running the Program is not restricted, and the output from the Program | |
156 | is covered only if its contents constitute a work based on the | |
157 | Program (independent of having been made by running the Program). | |
158 | Whether that is true depends on what the Program does. | |
159 | ||
160 | \item You may copy and distribute verbatim copies of the Program's source | |
161 | code as you receive it, in any medium, provided that you conspicuously | |
162 | and appropriately publish on each copy an appropriate copyright notice | |
163 | and disclaimer of warranty; keep intact all the notices that refer to | |
164 | this License and to the absence of any warranty; and give any other | |
165 | recipients of the Program a copy of this License along with the Program. | |
166 | ||
167 | You may charge a fee for the physical act of transferring a copy, and you | |
168 | may at your option offer warranty protection in exchange for a fee. | |
169 | ||
170 | \item | |
171 | ||
172 | You may modify your copy or copies of the Program or any portion | |
173 | of it, thus forming a work based on the Program, and copy and | |
174 | distribute such modifications or work under the terms of Section 1 | |
175 | above, provided that you also meet all of these conditions: | |
176 | ||
177 | \begin{enumerate} | |
178 | ||
179 | \item | |
180 | ||
181 | You must cause the modified files to carry prominent notices stating that | |
182 | you changed the files and the date of any change. | |
183 | ||
184 | \item | |
185 | ||
186 | You must cause any work that you distribute or publish, that in | |
187 | whole or in part contains or is derived from the Program or any | |
188 | part thereof, to be licensed as a whole at no charge to all third | |
189 | parties under the terms of this License. | |
190 | ||
191 | \item | |
192 | If the modified program normally reads commands interactively | |
193 | when run, you must cause it, when started running for such | |
194 | interactive use in the most ordinary way, to print or display an | |
195 | announcement including an appropriate copyright notice and a | |
196 | notice that there is no warranty (or else, saying that you provide | |
197 | a warranty) and that users may redistribute the program under | |
198 | these conditions, and telling the user how to view a copy of this | |
199 | License. (Exception: if the Program itself is interactive but | |
200 | does not normally print such an announcement, your work based on | |
201 | the Program is not required to print an announcement.) | |
202 | ||
203 | \end{enumerate} | |
204 | ||
205 | ||
206 | These requirements apply to the modified work as a whole. If | |
207 | identifiable sections of that work are not derived from the Program, | |
208 | and can be reasonably considered independent and separate works in | |
209 | themselves, then this License, and its terms, do not apply to those | |
210 | sections when you distribute them as separate works. But when you | |
211 | distribute the same sections as part of a whole which is a work based | |
212 | on the Program, the distribution of the whole must be on the terms of | |
213 | this License, whose permissions for other licensees extend to the | |
214 | entire whole, and thus to each and every part regardless of who wrote it. | |
215 | ||
216 | Thus, it is not the intent of this section to claim rights or contest | |
217 | your rights to work written entirely by you; rather, the intent is to | |
218 | exercise the right to control the distribution of derivative or | |
219 | collective works based on the Program. | |
220 | ||
221 | In addition, mere aggregation of another work not based on the Program | |
222 | with the Program (or with a work based on the Program) on a volume of | |
223 | a storage or distribution medium does not bring the other work under | |
224 | the scope of this License. | |
225 | ||
226 | \item | |
227 | You may copy and distribute the Program (or a work based on it, | |
228 | under Section 2) in object code or executable form under the terms of | |
229 | Sections 1 and 2 above provided that you also do one of the following: | |
230 | ||
231 | \begin{enumerate} | |
232 | ||
233 | \item | |
234 | ||
235 | Accompany it with the complete corresponding machine-readable | |
236 | source code, which must be distributed under the terms of Sections | |
237 | 1 and 2 above on a medium customarily used for software interchange; or, | |
238 | ||
239 | \item | |
240 | ||
241 | Accompany it with a written offer, valid for at least three | |
242 | years, to give any third party, for a charge no more than your | |
243 | cost of physically performing source distribution, a complete | |
244 | machine-readable copy of the corresponding source code, to be | |
245 | distributed under the terms of Sections 1 and 2 above on a medium | |
246 | customarily used for software interchange; or, | |
247 | ||
248 | \item | |
249 | ||
250 | Accompany it with the information you received as to the offer | |
251 | to distribute corresponding source code. (This alternative is | |
252 | allowed only for noncommercial distribution and only if you | |
253 | received the program in object code or executable form with such | |
254 | an offer, in accord with Subsection b above.) | |
255 | ||
256 | \end{enumerate} | |
257 | ||
258 | ||
259 | The source code for a work means the preferred form of the work for | |
260 | making modifications to it. For an executable work, complete source | |
261 | code means all the source code for all modules it contains, plus any | |
262 | associated interface definition files, plus the scripts used to | |
263 | control compilation and installation of the executable. However, as a | |
264 | special exception, the source code distributed need not include | |
265 | anything that is normally distributed (in either source or binary | |
266 | form) with the major components (compiler, kernel, and so on) of the | |
267 | operating system on which the executable runs, unless that component | |
268 | itself accompanies the executable. | |
269 | ||
270 | If distribution of executable or object code is made by offering | |
271 | access to copy from a designated place, then offering equivalent | |
272 | access to copy the source code from the same place counts as | |
273 | distribution of the source code, even though third parties are not | |
274 | compelled to copy the source along with the object code. | |
275 | ||
276 | \item | |
277 | You may not copy, modify, sublicense, or distribute the Program | |
278 | except as expressly provided under this License. Any attempt | |
279 | otherwise to copy, modify, sublicense or distribute the Program is | |
280 | void, and will automatically terminate your rights under this License. | |
281 | However, parties who have received copies, or rights, from you under | |
282 | this License will not have their licenses terminated so long as such | |
283 | parties remain in full compliance. | |
284 | ||
285 | \item | |
286 | You are not required to accept this License, since you have not | |
287 | signed it. However, nothing else grants you permission to modify or | |
288 | distribute the Program or its derivative works. These actions are | |
289 | prohibited by law if you do not accept this License. Therefore, by | |
290 | modifying or distributing the Program (or any work based on the | |
291 | Program), you indicate your acceptance of this License to do so, and | |
292 | all its terms and conditions for copying, distributing or modifying | |
293 | the Program or works based on it. | |
294 | ||
295 | \item | |
296 | Each time you redistribute the Program (or any work based on the | |
297 | Program), the recipient automatically receives a license from the | |
298 | original licensor to copy, distribute or modify the Program subject to | |
299 | these terms and conditions. You may not impose any further | |
300 | restrictions on the recipients' exercise of the rights granted herein. | |
301 | You are not responsible for enforcing compliance by third parties to | |
302 | this License. | |
303 | ||
304 | \item | |
305 | If, as a consequence of a court judgment or allegation of patent | |
306 | infringement or for any other reason (not limited to patent issues), | |
307 | conditions are imposed on you (whether by court order, agreement or | |
308 | otherwise) that contradict the conditions of this License, they do not | |
309 | excuse you from the conditions of this License. If you cannot | |
310 | distribute so as to satisfy simultaneously your obligations under this | |
311 | License and any other pertinent obligations, then as a consequence you | |
312 | may not distribute the Program at all. For example, if a patent | |
313 | license would not permit royalty-free redistribution of the Program by | |
314 | all those who receive copies directly or indirectly through you, then | |
315 | the only way you could satisfy both it and this License would be to | |
316 | refrain entirely from distribution of the Program. | |
317 | ||
318 | If any portion of this section is held invalid or unenforceable under | |
319 | any particular circumstance, the balance of the section is intended to | |
320 | apply and the section as a whole is intended to apply in other | |
321 | circumstances. | |
322 | ||
323 | It is not the purpose of this section to induce you to infringe any | |
324 | patents or other property right claims or to contest validity of any | |
325 | such claims; this section has the sole purpose of protecting the | |
326 | integrity of the free software distribution system, which is | |
327 | implemented by public license practices. Many people have made | |
328 | generous contributions to the wide range of software distributed | |
329 | through that system in reliance on consistent application of that | |
330 | system; it is up to the author/donor to decide if he or she is willing | |
331 | to distribute software through any other system and a licensee cannot | |
332 | impose that choice. | |
333 | ||
334 | This section is intended to make thoroughly clear what is believed to | |
335 | be a consequence of the rest of this License. | |
336 | ||
337 | \item | |
338 | If the distribution and/or use of the Program is restricted in | |
339 | certain countries either by patents or by copyrighted interfaces, the | |
340 | original copyright holder who places the Program under this License | |
341 | may add an explicit geographical distribution limitation excluding | |
342 | those countries, so that distribution is permitted only in or among | |
343 | countries not thus excluded. In such case, this License incorporates | |
344 | the limitation as if written in the body of this License. | |
345 | ||
346 | \item | |
347 | The Free Software Foundation may publish revised and/or new versions | |
348 | of the General Public License from time to time. Such new versions will | |
349 | be similar in spirit to the present version, but may differ in detail to | |
350 | address new problems or concerns. | |
351 | ||
352 | Each version is given a distinguishing version number. If the Program | |
353 | specifies a version number of this License which applies to it and ``any | |
354 | later version'', you have the option of following the terms and conditions | |
355 | either of that version or of any later version published by the Free | |
356 | Software Foundation. If the Program does not specify a version number of | |
357 | this License, you may choose any version ever published by the Free Software | |
358 | Foundation. | |
359 | ||
360 | \item | |
361 | If you wish to incorporate parts of the Program into other free | |
362 | programs whose distribution conditions are different, write to the author | |
363 | to ask for permission. For software which is copyrighted by the Free | |
364 | Software Foundation, write to the Free Software Foundation; we sometimes | |
365 | make exceptions for this. Our decision will be guided by the two goals | |
366 | of preserving the free status of all derivatives of our free software and | |
367 | of promoting the sharing and reuse of software generally. | |

407 | \section*{Appendix: How to Apply These Terms to Your New Programs} | |
408 | ||
409 | If you develop a new program, and you want it to be of the greatest | |
410 | possible use to the public, the best way to achieve this is to make it | |
411 | free software which everyone can redistribute and change under these | |
412 | terms. | |
413 | ||
414 | To do so, attach the following notices to the program. It is safest to | |
415 | attach them to the start of each source file to most effectively convey | |
416 | the exclusion of warranty; and each file should have at least the | |
417 | ``copyright'' line and a pointer to where the full notice is found. | |
418 | ||
419 | \begin{quote} | |
420 | one line to give the program's name and a brief idea of what it does. \\ | |
421 | Copyright (C) yyyy name of author \\ | |
422 | ||
423 | This program is free software; you can redistribute it and/or modify | |
424 | it under the terms of the GNU General Public License as published by | |
425 | the Free Software Foundation; either version 2 of the License, or | |
426 | (at your option) any later version. | |
427 | ||
428 | This program is distributed in the hope that it will be useful, | |
429 | but WITHOUT ANY WARRANTY; without even the implied warranty of | |
430 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the | |
431 | GNU General Public License for more details. | |
432 | ||
433 | You should have received a copy of the GNU General Public License | |
434 | along with this program; if not, write to the Free Software | |
435 | Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA. | |
436 | \end{quote} | |
437 | ||
438 | Also add information on how to contact you by electronic and paper mail. | |
439 | ||
440 | If the program is interactive, make it output a short notice like this | |
441 | when it starts in an interactive mode: | |
442 | ||
443 | \begin{quote} | |
444 | Gnomovision version 69, Copyright (C) yyyy name of author \\ | |
445 | Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. \\ | |
446 | This is free software, and you are welcome to redistribute it | |
447 | under certain conditions; type `show c' for details. | |
448 | \end{quote} | |
449 | ||
450 | ||
451 | The hypothetical commands {\tt show w} and {\tt show c} should show the | |
452 | appropriate parts of the General Public License. Of course, the commands | |
453 | you use may be called something other than {\tt show w} and {\tt show c}; | |
454 | they could even be mouse-clicks or menu items---whatever suits your | |
455 | program. | |
456 | ||
457 | You should also get your employer (if you work as a programmer) or your | |
458 | school, if any, to sign a ``copyright disclaimer'' for the program, if | |
459 | necessary. Here is a sample; alter the names: | |
460 | ||
461 | \begin{quote} | |
462 | Yoyodyne, Inc., hereby disclaims all copyright interest in the program \\ | |
463 | `Gnomovision' (which makes passes at compilers) written by James Hacker. \\ | |

467 | \end{quote} | |
468 | ||
469 | ||
470 | This General Public License does not permit incorporating your program | |
471 | into proprietary programs. If your program is a subroutine library, you | |
472 | may consider it more useful to permit linking proprietary applications | |
473 | with the library. If this is what you want to do, use the GNU Library | |
474 | General Public License instead of this License. | |
